A trend and monthly viewer of the monthly Ask HN: Who's Hiring?

I'm a long time ruby and rails developer living under the never ending fear of "rails is dead" every month, for the last 15 years or so. Does anyone know the feeling? There are a few aggregators and viewers out there, but I've wanted to build something polished and useful for viewing the HN data, so here it is, my take on the concept. Open and free.I'm looking to add a bit more utilitarian functionality, a configurable monthly emailer, direct job links, etc, in the future. Hope you find useful.
